You know you've got a great bit of software in front of you when you keeping finding things and thinking 'wow, that's really useful', and 'I didn't know they'd put that feature in'.

Well that's how I feel about DrumTrackHD. I've always like the iPhone/Touch version of the app and I was really pleased when the iPad version came out. The interface is very similar so the learning curve from one app to the other is quite short.

However there's plenty of features in the new HD version of this excellent drum machine. I've really enjoyed the additional screen space with the iPad version. It's made a big difference to workflow within this app.

One of the great things about DrumTrackHD is the level of control over each step in your pattern. Each step has individual volume, pan, pitch control and gives you just want to for you patterns especially with up to 16 tracks in the pattern too.

All of the export options that were there in the original, which makes it an easy addition to your existing workflow.

I also like the new FX in the app. Overall this is a great drum machine for the iPad and I hope that it will continue to get better and better.

Overall I like this app because it is simple to use with plenty of options to configure it

I've been playing with this app for a few days both on the iPad and iPhone, and it is a really nice app. Great for mucking about with some keyboard ideas or just doodling.

But that's not what I wanted to write about here. I was playing with the lessons in the app, and they are great fun. If anything I think these 'lessons' good go a lot further then they do now. I think that they would be great for game center. For kids the lessons are a great way to get them into trying to get better at playing songs.
